Factory Price 420 SS Arc Spraying Wire for Paper Roll Restoration and Corr

420 stainless steel arc spraying wire is a high-cost-performance alloy spraying
material provided by a professional alloy trading company, tailored to core
industrial needs. Made from 420 martensitic stainless steel raw materials with
a purity of over 99.9%, the wire undergoes precision wire drawing, vacuum
annealing, and precision straightening processes to ensure inherent performance
stability. During arc spraying, it forms a coating with a density of ≥95% and
a coating-substrate bonding strength of ≥35MPa, effectively resolving industry
pain points such as paper roll wear and metal substrate corrosion in harsh
environments. Leveraging our direct procurement supply chain, we offer factory-
direct pricing, and also support bulk customization and small-batch trial
orders to meet the diverse procurement and application demands of different
customers.

Product Features
Superior corrosion resistance: 13-14% chromium content forms a protective
passivation film, extending the substrate’s anti-corrosion cycle by 3-5 times.

High wear resistance & restoration capability: Coating microhardness reaches
HV550-700, enabling 0.1-5mm precise thickness restoration for damaged paper
rolls.

Excellent process compatibility: ±0.02mm diameter tolerance, stable melting
and arc combustion, ≤3% splash rate, and compatibility with mainstream
spraying equipment.

Outstanding cost-effectiveness: Factory-direct pricing, ≤2% loss rate, 1.2-1.5
㎡ coverage per kg, and 15-20% lower comprehensive cost than similar products.

Environmental compliance: Complies with ISO 9001 and RoHS standards, free of
harmful impurities and toxic emissions after spraying.

Stable batch consistency: Three full inspections per batch ensure uniform
diameter, hardness, and composition of products.

Product Applications
Paper roll restoration & strengthening: Repairs and reinforces papermaking
machine rolls (press, guide, coating rolls), restoring roundness error to
≤0.02mm and extending service life by over 3 times.

General metal substrate corrosion protection: Protects carbon steel, cast iron
and other substrates in machinery, chemical, marine, and bridge fields from
oxidation and chemical erosion.

Wear-resistant component strengthening: Increases the surface hardness of
mining, agricultural, and printing equipment parts by 2-3 times, reducing wear
and replacement costs.

Special industry applications: Applicable to automotive chassis repair, medical
device protection, electronic shell corrosion prevention, and food machinery
surface strengthening.
